COMBINATION-FAUCET.

Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed December 22, 1914. Serial No. 878,554.

To all whom it may concern:

Be it known that I, FRANK M. WRIGHT, citizen of the United States,residing at T- peka, in the county of Shawnee and Stateof (ansas, haveinvented certain new and useful Improvements in Combination-Faucets, ofwhich the following is a specification.

My invention is designed as an improved double acting or combinationfaucet, and as its primary object contemplates a faucet having both ahot and a cold water inlet and a single discharge outlet, the former twobeing open to the latter whereby to provide, through operation of anovel valve device, for a discharge of water, either hot, cold, orintermediate the two extremes.

To acquire a knowledge of the details of construction of the means foreffecting the mentioned result, reference is to be had to the followingdescription and accompanying drawings, in which- Figure 1 is alongitudinal sectional view of a faucet constructed in accordance withthe-present invention; Fig. 2 is a front elevation; Fig. 3 is a viewsimilar to Fig. 1, the section however being taken transversely thereto;and Fig. at is a central cross sectional view.

Like reference numerals designate like parts throughout the severalviews.

5 designates as an entirety, the faucet casing, said casing having acold water inlet opening 6, a hot water inlet opening 7, and a commondischarge or outlet 8. A passage way 9 connects the opening 6 with avalve chamber 10 while a similarly formed passage way 11 connects theopening 7 with a like valve chamber 12, said two valve chambers 10 and12 being formed at the opposite ends of the casing 5 and preferably inalinement as shown. The chamber 10 is open to the outlet 8 as indicatedat 13 and chamber 12 is open to said outlet as indicated at 14, sucharrangement providing, in use, a common outlet or discharge.

The casing 5 is enlarged at a point preferably equi-distant from itsterminals to form a chamber 15 non-communicant with the chambers 10 and12 mentioned before. One face, or rather one of the chamber walls ismade removable and designated 16, the said wall being constructed toform a hearing 17 within which one end of a shaft 18, arrangedconcentric to the chamber 15, is journaled. Said shaft 18 penetrates theopposite or integral wall of the chamber and ed position by means oflock nuts carries at its outer terminal a handle 19 by means of whichsaid shaft may be rotated as desired. Said handle, as indicated to advantage in Fig. 2, has formed thereon or attached thereto an indicator20 which, upon movement of the handle, is adapted to traverse a dial 21formed on the exterior face of the integral wall of chamber 15.

An operating cam or disk 22 is mounted on the shaft 18 and recessed toform lugs or contact projections 23, 24 and 25, the latter of saidcontact projections being greater in its diameter than the precedingtwo. Disk 22 is keyed or otherwise affixed to the shaft 18 that it maybe rotated therewith. A spring 26 is arranged to embrace the shaft 18and to abut respectively the mentioned disk and the removable chamberwall, said spring maintaining the disk in the manner desired.

At diametrically opposite points relatively to the chamber 15 andextending thereinto,1 provide rollers 27 and 28, the former beingmounted in the'bifurcated and enlarged end 29 of a valve operating stem30, the said stem being threaded throughout a portion of its length toprovide for the arrangement thereon of an adjustable valve member 31.Valve member 31 operates within chamber 10 and is held in its adj ust-Said valve is movable into and out of engagement with a valve seat 33formed at the point where chamber 10 is open to the pastsage way 13. Theroller 28, as hereinbeforc suggested is situated at a pointdiametrically opposite to the roller 27 and is mounted on the enlargedbifurcated end 34 of a valve stem 35, said valve stem being threadedthroughout a portion of its length to mount a valve member 36 adjustablethereon and movable with the stem into and out of engagement with a seat37 formed at a point where chamber 12 is open to the passage way 1 1.The valve stems and are respectively slidably mounted in bearingportions 30 and 35 of the casing 5. Valve member 36 may also be lockedin its adjusted position by means of lock nuts 38. Enlargements 29 and31 are located within chambers 29' and 34' of easing 5 and whichchambers communicate with chamber 15.

s a means for holding the valves 31 and 36 in engagement with theirrespective valve seats 33 and 37, I provide suitable springs 39 and 40,the former being arranged to embrace the stem and to abut theenlargement 2 and the casing wall and the latter, arranged to embracethe. stem and to abut the enlargement 34 and the casing wall. Removable. plugs 41 may be provided as a means for gaiping access to thevalves of the device should occasion demand.

In assembling the parts, plate 16 is removed to open chamber 15whereupon valve stems 30 and 35 minus valves 31 and 36 and nuts 32, 3'3,37 and 38, are inserted into the chamber, thence tilted and insertedinto chambers 29 and 31' and finally through the openings in bearingportions 30 and 35. Thereafter the valves 31 and 36 as well as nuts 32,33, 37 and 38 are applied to the stems.

In operation,- should a supply of cold water be desired, handle 19 isturned to register the indicator 20 with that point on the dialdesignated cold, in which event disk 22 is rotated until contact point24 engages roller 27, and, by the pressure exerted thereon, causes valvestem 30 to move relatively to the casing 5 sufiiciently to disengagevalve 31 from its seat 33. As the valve begins to recede from its seatupon rotation of the disk 22, communication is opened between chamber 10and passage way 13 thus permitting an unchecked flow of cold water fromthe inlet 6 to the outlet or discharge 8. Should hot water he desired,handle 19 is manipulated to register the indicator 20 with the word hoton the dial, such movement of the handle causing the disk to be turneduntil the contact point 25 engages the roller 28 with suflicient forceto move stem 35 against the tension of its associated spring 40 andvalve 36 out of engagement with its seat 37 thus connecting chamber 12and passage way 14. Valve 36 having thus been moved, it is evident thatan unobstructed passage way for warm water is effected. It is to benoted that the contact point or projection 25 is comparatively large inorder that it may remain in engagement with the roller 28 while contactpoint or projection 23 is out of engagement with roller 27, thisarrangement providing for a discharge of hot water without movement ofvalve 31. To draw a supply of water (hot and cold mixed) it-is butnecessary to move the handle sufficiently to cause the indicator 20 toregister with warm on the dial, in which event the disk is turned to theposition indicated in Fig. 1 or sufiiciently to cause the contact point23 to engage the roller 27 and at the same time the contact point 25 toengage the roller 28, such engagement causing both of the valves 31 and36 to move out of engagement with their respective valve seats andcommunication to.

be opened from the inlet 6 to the outlet 8 and from the inlet 7 to saidoutlet, hot water mtermmghng with the cold water at the juncture of theoutlet 8 and the passage ways 1 and 14- leading thereto. 'lo shut otlthe water supply entirely, the handle is moved .into either of itsextreme positions so that the indicator 20 will register with off on thedial, such movement of the handle causing the disk to be correspondinglyrotated until the several contact points are entirely out of engagementwith the two rollers 27 and 28, in which event the springs 39 and all)will not automatically to close communication respectively between thechamber 10 and the passage way 13' and the chamber 12 and the passageway 14, thus effectually cutting off both the hot and cold water supply.

From the foregoing, taken in connection with the accompanying drawingsit will be noted that water of a varying temperature may be supplied tothe outlet 8 through gradual movement of the handle 19; that the valvesact automatically to cut off the water supply the moment the severalcontacts disengage the rollers mounted on the respective valve stems;and that a uniform and compact valve structure has been provided throughthe arrangement of the valves as hereinbefore described, both beingactuatable through rotation of but a single disk.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in the above description, asthe preferred embodiment, is the most efficient and practical; yetrealizing that the conditions concurrent with the adoption of my devicewill necessarily vary, 100 I desire to emphasize the fact that variousminor changes in details of construction, proportion and arrangement ofparts may be resorted to, when required, without sacrificing any of theadvantages of my inven- 105 tion, as defined in the appended claims.
